Currently, Proton Mail's Automatic Transfer allow filtering emails set to transfer by Object, Sender or Attached file

I would like to transfer only emails sent to a particular address or alias.

Use case: I'd like to transfer all the newsletters I receive on newsletters@myprotondomain.fr to a Gmail address
Some of them are sent directly, others via Proton or Relay alias

I'd be able to generate automated AI summaries of my newsletters using Make or other tools that easily connect to Gmail, without sending my private emails to Google...

Another use case would be transfering newsletters to a reader app like Mailscribe https://mailscribe.com/inbox
